Problems solved by technology

For multi-layer solid wood composite flooring, there are many layers of base material, and the multi-layer veneer is laminated, the flatness of the board is greatly reduced, and the appearance is not very beautiful. At the same time, the amount of glue is large, which destroys the original natural characteristics of the wood.
The panels of three-layer solid wood composite flooring generally use precious wood. Although the number of layers is small, the utilization rate of precious wood is reduced, and the cost is also increased to a certain extent.
The patent with the application number CN200610086625.X discloses a five-layer thick core solid wood composite floor and its manufacturing method. It proposes to bond a layer of thin plates to the bottom and bottom of the core plate, thereby overcoming the tendency of the surface layer of the five-layer thick core floor to be degummed. and the wave phenomenon
In the patent application number CN201210418949.4, a modified soybean protein glue and its application in the production of solid wood composite flooring are disclosed. , the amount of double-sided glue is controlled at 350-420g / m 2 , when this process produces conventional solid wood composite flooring composed of veneers with a thickness of less than 2.6mm, it can ensure the floor bonding strength and water resistance, but there are still problems in the bonding of rotary cut boards with a thickness of more than 7.5mm

preparation example Construction

[0031] The present invention also provides a preparation method of thick-core solid wood composite flooring, comprising the following steps:

[0032] S1, provide rotary solid wood with a thickness of 7.5-11mm as the solid wood core board, and coat soybean formaldehyde-free glue on both sides of the solid wood core board;

[0033] S2, pasting the first veneer and the second veneer on both sides of the solid wood core board, forming embryos according to the vertical direction of the wood grain texture, and performing cold pressing and hot pressing in sequence after the embryo formation to obtain a thick core substrate;

[0034] S3, coating soybean formaldehyde-free glue on both sides of the thick core substrate;

[0035]S4, paste the bottom plate on one side of the first veneer of the thick core substrate, paste the panel on the side of the second veneer of the thick core substrate, perform cold pressing and hot pressing in sequence after the embryo formation, and obtain a solid...

Embodiment 1

[0043] Thick core parquet is prepared using the following steps:

[0044] (1) Provide rotary-cut pine wood with a thickness of 7.5mm as the solid wood core board. The moisture content of the solid wood core board is controlled at about 12%. Glue on both sides with soybean formaldehyde-free glue on the rubber roller. The amount of glue applied on each side Controlled at (310±5)g / m 2 ;

[0045] (2) Paste eucalyptus veneers with a thickness of 3.6mm on both sides of the glue-coated solid wood core board. The moisture content of the eucalyptus veneer is controlled at about 10%, and the embryos are formed according to the vertical direction of the wood grain, and the embryos are completed. Within 60 minutes, put it into a cold press for cold pressing, the cold pressing time is 50 minutes, and the cold pressing pressure is 7kg / cm 2 , and then repair the cold-pressed slab above, within 6 hours after the repair is completed, put it into a hot press for hot pressing, the hot pressing...

Embodiment 2

[0049] Thick core parquet is prepared using the following steps:

[0050] (1) Provide rotary-cut pine wood with a thickness of 7.5mm as the solid wood core board. The moisture content of the solid wood core board is controlled at about 12%. Glue on both sides with soybean formaldehyde-free glue on the rubber roller. The amount of glue applied on each side Controlled at (230±5)g / m 2 ;

[0051] (2) Paste eucalyptus veneers with a thickness of 3.6mm on both sides of the glue-coated solid wood core board. The moisture content of the eucalyptus veneer is controlled at about 10%, and the embryos are formed according to the vertical direction of the wood grain, and the embryos are completed. Within 60 minutes, put it into a cold press for cold pressing, the cold pressing time is 50 minutes, and the cold pressing pressure is 7kg / cm 2 , and then repair the cold-pressed slab above, within 6 hours after the repair is completed, put it into a hot press for hot pressing, the hot pressing...

Abstract

The invention discloses a thick-core solid wood composite floor and a preparation method thereof. The thick-core solid wood composite floor comprises a bottom plate, a first single plate, a solid woodcore plate, a second single plate and a face plate which are sequentially arranged from bottom to top, all layers of plates are bonded through soybean non-formaldehyde glue, and the solid wood core plate is made of rotary-cut solid wood. The special filling characteristic and curing characteristic of the soybean non-formaldehyde glue are utilized, the problem that the water resistance of the thick-core floor is unqualified due to large and deep burr groove marks in the surface of the thick-core plate of the rotary-cut pine wood is solved, and the mechanical property and the water resistance of the thick-core floor are improved. The thick-core solid wood composite floor is free of formaldehyde and meets the requirement for environmental protection. The preparation method of the thick-coresolid wood composite floor is simple, convenient to operate and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of solid wood composite flooring, in particular to a thick-core solid wood composite floor and a preparation method thereof. Background technique [0002] Solid wood composite flooring is generally based on multi-layer solid wood composite flooring and three-layer structure solid wood composite flooring. For multi-layer solid wood composite flooring, there are many layers of base material, and the multi-layer veneer is laminated, the flatness of the board is greatly reduced, and the appearance is not very beautiful. At the same time, the amount of glue is large, which destroys the original natural characteristics of the wood. The panels of three-layer solid wood composite flooring generally use precious wood. Although the number of layers is small, the utilization rate of precious wood is reduced, and the cost is also increased to a certain extent. [0003] Solid wood thick-core flooring adopts a symmetrica...
